Product Q&A
Q:Are oil-immersed transformers only suitable for outdoor use?
A:
No. Oil-immersed transformers can be installed outdoors, indoors, and in box substations. With excellent heat dissipation and overload performance, they're widely used in power grid and industrial scenarios, and can work indoors with proper ventilation and fire protection.
Q:Is noise during operation of oil-immersed transformers a fault?
A:
Steady humming is normal electromagnetic noise. Sharp sounds, intense vibration, and unstable noise suggest abnormal operation from core looseness, unbalanced load, or abnormal voltage, needing timely maintenance.
Q:Does transformer oil need regular replacement?
A:
Frequent replacement isn't required. It needs regular quality testing, impurity filtration, and dehumidification. Replacement is needed only if the oil is severely aged, damp, carbonized, or fails insulation standards.
Q:What are the core advantages of oil-immersed transformers compared with dry-type transformers?
A:
They offer higher heat dissipation efficiency, larger heat capacity, stronger overload resistance, longer service life, and lower maintenance costs, making them more suitable for high-power, long-term continuous operation in industrial and power grid conditions.
Q:Can oil-immersed transformers operate under full load for a long time?
A:
Yes. Standard oil-immersed transformers support long-term continuous operation at rated load with short-time overload margin. They operate stably and continuously with qualified oil quality and good heat dissipation and ventilation.
